Double-Ball Rubber Expansion Joint

1. Rubber Joint reasonable structure; High flexibility
2. Rubber: EPDM NBR NR CR IIR
3. Pressure: 0, 6-1.6MPa
4. Good quanlity&cheap

Flexible Rubber Joint Features and Benefits:

1. Absorbs Directional Movement
2. Less Turbulence or Material Entrapment
3. Absorbs Vibration, Noise and Shock

Features:
1. This product could primarily reduce the vibration and the noise of the piping system, completely solve the different piping problems as displace of joint, axial flex and etc.
2. According to different material requirement, product could be made as acid proof, corrosion proof to suit different medium and environments.
3. The materials are good sealing, light weighting, easy to fix and maintain, also has long-working expecting. But please keep far away from sharp metal in order to avoid breaking of the rubber body.
4. For flanges of other standards or non-standards. It is necessary to be agreed upon separately. Please specify standard of furnish diagram and relative parameter. We will manufacture accordingly. Rubber material may be selected according t your requirement.
5. Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.
6. Double sphere flange end rubber joint: The rubber body has two bridges. It can bear more pressure and the length is long than single sphere rubber joint.
7. The size can made as customer's drawing, we can make mould for special type.
8. They are cost effective, the total cost is low because of rubber is cheap and it have long use life.

Our products have the following character:
Good select materials, advanced equipment, skillful workmanship, rigorous quality control standards, attractive design and durability. They are well-known for excellent quality, most competitive price, and lower cost and prompt delivery.
The product is made up of the composite rubber ball, including internal rubber layer, nylon fabric, and external rubber layer and the loose metal flange. With the merits of high pressure, stable elasticity, big displacement, good damping capacity and noise reduction, it is widely used in the systems of water supply, drainage, water circulation, heating and ventilating, and air conditioning, and the piping systems of the paper-making, the petrochemical industry, marine, compressors pumps, fans, etc

Delivery time:
Within 30 days after receipt of the deposit, or as your request

Packaging details:
Unfumigation wooden case (out package) and plastic film and textile membrane(inside package). We can make change as your request.
